You obviously didn't do what I told you to. It should say 1.7.0_xx if you downgraded to Java 7

Curse PremiumThat's the fifth line of your crash report.
See that bold bit at the end?
That means you have Java 8 installed.

Curse PremiumJava 8 is breaking forge.
Do not install it
Do not reinstall it
If your using java 8 fine, that is because your not using forge.
If you want to use forge, downgrade to java 7.
Or to say Google and realize that only Java 8 u20+ breaks forge builds below build 1217.
http://www.java.com/en/download/help/uninstall_java.xml
It is impossible to rephrase it into a more ELI5 format.
After following that word for word for Windows.
Install this. (Java 7 86x u71)
http://javadl.sun.com/webapps/download/AutoDL?BundleId=97807
Then this. (Java 7 x64 u71).
http://javadl.sun.com/webapps/download/AutoDL?BundleId=97809
That is all there is. That is all it takes. If you have problems still. MCF members can't really help further.
